Fix passing a const array to parse (#258) 
Fixes #257. The input array is not modified, so we can declare this as
`char const* const*`.

Jarryd Beck fedf9d7b57 Refactor parser 
Major refactor of the parsing code organisation to improve encapsulation
and not modify the input arguments. The returned result no longer has
pointers into the original option specification.

Support 'const char**' arguments in Options::parse (#250) 
`cxxopts` doesn't modify the contents of the argv strings. This changes
the parse function to take a reference to a `const char**`.

Fixes #245: Mention the option name when throwing on "no value" (#246) 
* Fixes #245:

* Added a new exception type: `option_has_no_value_exception`; throwing it when an option has no value we can cast with `as()`, instead of an `std::domain_error`.
* The `OptionValue` type now holds a pointer to the long option name (in its corresponding key within ParseResults's `m_results` field.

linus-sherrill 9910095719 Remove check for container when generating help message. (#170) 
Some positional parameters would be listed in the help text and others
would not, when what is desired is that no positional parameters are
listed with the other command options. This change suppresses the help
listing for all positional parameters.

Jarryd Beck 5da5d67111 Throw exception on invalid positional argument 
Fixes #169. It seems reasonable to throw an exception when an attempt is
made to parse into positional parameters that don't exist.

le-migou 48e265dc4b Remove `u8` prefix in string literals. (#172) 
String literals with the prefix `u8` now have the type `const char8_t[N]` in
C++20. As a consequence the library does not compile in c++2a mode with GCC
(you can't concatenate `std::basic_string<char>` and `const char8_t[]` as
`char` and `char8_t` are different types).

linus-sherrill 9990f73845 Remove empty string initializer. (#159) 
The empty string caused the vector to have one element which caused
the test at line 2041 to always fail.

舒俊杰 5950d78558 fix min/max defined macros (#152) 
Windows is broken and defines `min` and `max` as a macro, adding parentheses stops them from being expanded.

Fixes #124.
 2018-11-19 17:45:51 +11:00
Jarryd Beck c713b44d92 Use a shared pointer for the options map 
Fixes #132. Since the map of options is shared between Options and
ParseResult, they should use a shared pointer instead of a reference so
that ParseResult can be returned without referencing destroyed memory.

Jarryd Beck cde83be99b Fix version numbering in CMakeLists.txt 
Fixes #115. Read the version number out of `cxxopts.hpp` instead of
having to duplicate it in CMakeLists.txt.

Jarryd Beck e725ea3084 Use unsigned type for integer digit 
Fixes #109. Although we always used numbers in the ASCII range, it was
in a `size_t`, leading to a warning about possible loss of data on some
compilers.

Jarryd Beck e40645e084 Don't show default when boolean false 
Fixes #102. Don't show the default value when it is a boolean and the
value is false. Note that this is a bit of a hack and the
implementation should probably be reevaluated in the future.
 2018-03-08 08:53:26 +11:00
Jarryd Beck 76bd60dc17 Add support for std::optional
